An expert on TikTok, known as @tatechtips, explained just how to access it.
First, you’ll need to open up your phone call app. Once there, the TikToker walks us through what to do.
He said: “If you have an Android and you type in Star, Hash, Zero, Star, Hash, you get this secret hidden diagnostics menu, so from here you can diagnose any issues you might have.”
The phone display changes into different options that you can choose from to look at how specific parts of your device are operating.

The TikToker continued: “You can check your front camera, you can test your speaker, and you can also make sure the colors in your screen are all working nice and bright.
“Give it a try. Make sure your phone's tip top.”
Trying it out for themselves, viewers of the video took to the TikTok comment section to share their reactions to the feature.

This prompted a reply from someone else who’d had the same problem, saying: “Nearly died, just press power button often to activate emergency call, then will be out.”
And a third person added: “Yeah me too!! I nearly had a heart attack as it wouldn't exit!! I just pressed power off and it worked! Thank god.”
